Z10 browser text scaling issue..

Hi! I am new to BlackBerry, just got my first BB device, Z10 a week ago.

So far my biggest problem is that the browser, which everyone said to be really great, is not really great. Okay, it is fast and has flash support, but..
I have a weird problem with multiple different pages. Text is not scaling too well, and it is sometimes barely readable.
Here is some screens from my problem.
Text size set to 6 it is almost readable, but not a pleasure to read. When size is set to 8, it makes it even harder to read. The last picture is taken with alternative browser, Naija browser, which seems to handle this kind of issue no problem. Naija browser has it own problems, and I'd rather use the native browser.
Is there anything to do with this? Reader mode doesn't work with all sites, and I don't even like using it. I am running the latest 10.2.1.2977 OS.

As ai said in OP, Naija Browser for BB did it like it should be done. (last pic)
Also my old Android stock browser, Dolphin Browser and Firefox for Android had no problem showing it. I have never had similar problem with any site or device.
